They brought new ideas to the less-developed villages.
A．have been encouraged; bigger and bigger
B．has been encouraged; bigger and bigger
C．have encouraged; more and more
D．has encouraging; more and more
答案
答案：A
题目分析：句意：--许多大学生已经被鼓励去中国的农村地区工作。--是的，我们称这个为“大学生村官工程”。这个数字变得越来越大。分析考查：a number of 许多，大量的；本句后接可数名词复数，因此用have;分析：越来越大，为比较级+and+比较级的形式，人数的增加用形容词big,因此选择bigger and bigger.故选A
